I can hardly recall another winter which saw so little by way of even any frost, let alone snow. |

Highlights of the winter was Boxing Day evening with the best rain to snow transistion for some years. It was rapid and the snow accumulated almost the moment when transistion was complete. After what was a disappointing overnight period, the snow finally fell the next morning. Despite the wet ground, snow accumulated easily. 29th January. That night, there was the polar low, some despute over whether it was actually one but it delivered snow here Not convince we will see much now before the meteorological winter ends. |

Not exactly on topic, but a spring discussion thread rarely fares well on TWO so I'll stick this here: That's a pretty strong signal emerging for March from the CFS model. It translates to surface highs more toward Central/Eastern Europe with surface lows running close to the NW of the UK. Potentially chilly at times if an easterly flow has any influence early in the month, otherwise a good chance of increasingly above average temperatures in a SW flow with variable surface conditions in the UK, driest in the SE. Usual caveats apply - only one model, LRFs are often a bit hopeless, etc. Looking on an broader time scale, here's the Met Office ensemble mean outlook for SLP across spring 2015 as a whole: Another strong signal, this time for the Azores High to be strong and often displaced or ridging across the UK. By contrast, the January update had a fairly strong negative pressure anomaly centered over Scotland. Though this was for Feb-Apr rather than Mar-May, it still suggests a fairly big shift in the model's ideas for a fairly large part of spring. As usual, a similar setup then persists with only slight changes when looking at the Apr-Jun and May-Jul maps. Overall, that would be a very dry outcome for the SW in particular, but then this model suite does seem to have a habit of sticking with the same idea for months on end. I do wish we could freely see mean charts for the upcoming month in isolation, but I guess they feel that would take some value away from the pay-to-access products that offer such focus.

Background conditions for these winters 1974-75 Low sunspot number, East QBO, weak La Niña, a November Canadian warming, January monthly mean temp. at 90N at 30hpa: -65C 1978-79 High sunspot number, West QBO, neutral ENSO, cold November mean 30hpa, temp., a December Canadian warming, January monthly mean temp. at 90N at 30hpa: -75C Yet 1974-75 is one of the mildest winters on record and 1978-79 was a severe winter. |

There is an issue with what I call 'cold without reward' in which conditions are notably cold but not quite enough for decent snow to fall and accumulate. This winter had a fair bit of that, though on some occasions hard frosts were of some interest and kept the mood higher than it could have been. February, though, barely managed more than a few slight frosts beyond that promising start with a morning of lying snow. That one event saved it from being the least interesting month I've ever known. At least there was plenty of sunshine, in fact it's been two record-breaking winters of sunshine down here, with this year beating last by just 0.9 hours. |

Anyway, this winter was consistently *cool* and only actually cold for one brief spell. We had - I think - 3 occasions of lying snow, with the unexpected 2-3cm on Boxing Day the best. But on each occasion the snow was far too shortlived; on BD for instance it turned to rain toward the end of the period of PPN and halved the depth into a slush-fest A really frustrating winter to experience. |

I think this winter more than any recent winter has been dependent on location. I think that was due to the marginality and the polar maritime airmases that occurred more often than recent winters. Snow covered the field behind me in total for 7 days. Patches of snow lasted in the back garden in total for nearly a fortnight. I don't recall March 2001 delivering a snow event here. I remember the snow coming from that frontal system pushing up from the south but it never stuck at least here. Edited by user 08 March 2015 06:34:36(UTC)

Where my dad cleared his drive, the snow-pile stuck around for about a fortnight (it became a running joke) It just seemed the wrong side of marginal, as you say, for anything interesting to be sustained. I remember the Dec 09 (and indeed the Xmas 04) snowfall being from PM air - characterised here by a mixing in of snow pellets. This time, even though the local atmospheric parameters seemed very similar, what fell from the sky was too often rain/sleet instead of snow. Originally Posted by: KevBrads1  I don't recall March 2001 delivering a snow event here.

I remember going to Haigh Hall near Wigan that day and they had about 15cm. Our snow cover didn't last much beyond the next day. But, given the great snowfall on the preceding 29th Dec, and the snow-drought that had come in the winters before, it was a winter that stuck in the mind. |

I remember the snow coming from that frontal system pushing up from the south but it never stuck at least here. Yes I've never known a region to have such differences within just a few miles. Early 2013 was an example when people in south Manchester had almost zero snow all Winter yet we had quite a lot that Winter here in this part of Oldham spread out.... there was quite a bit of easterly winds/continental influence that Winter - I like easterlys in this part of the region they more often than not deliver. For more western and southern parts of the region I would imagine a NW'y is the best direction especially with those Cheshire gap type scenarios... As you know from experience it's not elevation that always makes the difference it can be wind direction too. I think the further west in the region people live they are more at risk of the Irish sea moderating snow as well, making it more sleety as well, the Irish sea is milder than the North sea. |

I've realised that, in many set-ups, there's no prescriptive methodology when it comes to forecasting snow in particular locales. Yes, the odds are that Buxton and other high-altitude places will get snow anyway. But we've had snow here in St Helens when other neighbouring areas have had none. Until 2013, I never had much hope for snow from an easterly, yet we had 2 or 3 events in Jan/Mar where further east toward Manchester there was little/no snow, yet here further west we got a few decent dumpings. Similarly, we've benefitted from a NW'ly off the Irish Sea (track is around 20 miles to the sea from here looking NW'wards) with heavier/more sustained snow at times than further inland, yet other times we've had sleet/wet snow/even rain when further inland has had snow. I've learnt to not expect anything (but sulk if we don't get snow and others do ) |

I've learnt to not expect anything (but sulk if we don't get snow and others do ) One thing is for sure considering we are closer to the North Pole than we are to the Equator we should do a heck of a lot better with cold & snow, in fact any where North of 45 degrees should be guaranteed to have long cold & snowy Winters, yet we are almost 10 degrees North of that but it's still like pot luck. Of course the Gulf Stream is one of the biggest culprits in terms of us getting a decent Winter and another 10 things like the natural cycle of west to east cyclogensis giving us milder air off the Atlantic instead of east to west off the much colder continent and Siberia. |
